All 14 systematic reviews undertaken by authors with histories of alcohol industry funding identified a cardioprotective effect of alcohol

Monday, October 11th, 2021

Researchers conducted a co-authorship network analysis of systematic reviews on the impacts on alcohol on cardiovascular disease (CVD) in order to investigate patterns of co-authorship in the literature, with particular attention given to industry funding:

60 systematic reviews with 231 unique authors met our inclusion criteria. 14 systematic reviews were undertaken by authors with histories of alcohol industry funding, including 5 that were funded directly by the alcohol industry itself. All 14 such reviews identified a cardioprotective effect of alcohol. These formed distinct co-authorship subnetworks within the literature. Of reviews by authors with no prior histories of alcohol industry funding, the findings were mixed, with 54% (25/46) concluding there was evidence of health protective effects.

We want to replace much more than 100% of current gas, coal, and oil with zero-carbon sources of electricity

Sunday, October 10th, 2021

Over the centuries, Matthew Yglesias reminds us, people have invented many different kinds of machines that help us do things and improve living standards:

But in a very general way, what most of these inventions do is let us substitute some form of power for human effort. And as long as we were totally ignoring the costs of burning coal and oil, this was a great mechanism for progress — you invent new ways to do things by burning coal and oil, so then you burn more coal and oil.

But since the mid-1970s we’ve been increasingly aware of the limits and problems with this model, and it’s put us on an energy diet. Now when we invent something cool, we often have to say “too bad the energy requirements are so high.”

But as Ryan Avent (from whom I borrowed that chart) and others have written, this is a backward way of looking at things. The turn toward conservation and efficiency was a necessary evil in an era when we couldn’t come up with a better way to deal with geopolitical instability linked to oil and pollution linked to all forms of fossil fuels.

Instead, we should raise our clean energy production ambitions. We don’t want to replace 100% of our current dirty energy — we want to generate vastly more energy than we are currently using and make it zero carbon.

What difference does it make in how you look at it?

In the “energy is a necessary evil” frame, we look at our current electricity needs and then ask, “How can we generate all that from zero-carbon sources?” In the alternate framing, you say that to the extent we can develop affordable, zero-carbon sources of electricity, we want to generate tons and tons of electricity. Ideally, we would want to replace much more than 100% of current gas, coal, and oil with zero-carbon sources of electricity and use that to literally power a bold new era of rapid economic growth.

I find that this vision tends not to be intuitively compelling to a lot of people who are accustomed to living in the efficiency era. But let’s just imagine a world with small modular nuclear reactors and advanced geothermal energy production — a world in which we have plenty of baseline power. As our ability to make batteries gets better and better, we can put them all in vehicles rather than using them to address intermittent renewables. Then when the sun shines or the wind blows, we have even more power that we can use for stuff that doesn’t need to be on all the time. It’s a world of energy abundance — Lewis Strauss’ dream of electricity that’s “too cheap to meter.”

John Lennon was embarrassed by his former radicalism

Saturday, October 9th, 2021

Today is John Lennon’s birthday, and I’d like to once again remind people that by 1979 Lennon was embarrassed by his former radicalism — at least according to Fred Seaman, who was his assistant at the time:

John, basically, made it very clear that if he were an American he would vote for Reagan because he was really sour on Jimmy Carter.

[...]

I also saw John embark in some really brutal arguments with my uncle, who’s an old-time communist… He enjoyed really provoking my uncle… Maybe he was being provocative… but it was pretty obvious to me he had moved away from his earlier radicalism.

He was a very different person back in 1979 and 80 than he’d been when he wrote Imagine. By 1979 he looked back on that guy and was embarrassed by that guy’s naivete.

He would not respect rules and regulations that threatened to prevent him from achieving his mission objectives

Thursday, October 7th, 2021

The troops and officers from some of the least belligerent nations in the world — namely, Sweden, Denmark, and Norway — turned out to be quite adept at both using force and playing the odds in the high-stakes political game played in Bosnia:

In late 1993, a reinforced Swedish-Danish-Norwegian mechanized battalion (Nordbat 2) deployed to Bosnia as part of an ongoing UN peacekeeping mission, known as UNPROFOR (United Nations Protection Force). The battalion was under Swedish command, and with the exception of a Danish tank company and a Norwegian helicopter detachment, was comprised of Swedish former conscripts, led by active-duty officers. The former conscripts had volunteered to return from civilian life to serve in a professional capacity. These Swedish troops, coming from a nation that had not experienced war for almost 200 years, faced a rigid UN bureaucracy, an unclear mandate, and the UN-imposed rules of engagement bordered on the absurd. However, the Swedes had one thing the others didn’t: a culture of mission command that had grown and developed for decades.

[…]

The Swedish Armed Forces were consequently trained to respond to a massive Soviet invasion force, which was expected to attack over land (via Finland), across the Baltic Sea, and by deploying airborne units. The Swedish Army estimated that a breakdown of command and control was a likely scenario as the Soviets would inevitably disrupt communications, destroy command centers, and seize territory, thereby isolating segments of the Swedish Army. In order to cope with this contingency, all units were trained to engage in what was known as “the free war,” (i.e. autonomous operations against local targets, without centralized command). The free war was intended as a last resort, which would only end when the invader had finally retreated. The official doctrine stated that all Swedish citizens were to, without exception, consider any order to surrender to be false, regardless of its origin. This was even printed in all phone books, which also contained instructions for the civilian population in case of war.

Considering that all Swedish Army units were expected to be able to operate autonomously, the culture of mission command completely permeated the entire organization. The officers and non-commissioned officers (NCOs), all the way down to the lowest-ranking enlisted men, were taught that the only truly mortal sin was to hesitate. To seize the initiative and act was the primary imperative. There was no priority higher than that of achieving the mission objectives at hand. Orders could be disobeyed, rules could be broken—as long as the mission was successful.

The battalion commanders who deployed to Bosnia to take charge of Nordbat 2 had spent their entire professional lives in this culture, and their men had known it since the earliest days of their own military training. To them, it was as natural as breathing.

[…]

Shortly after it had been deployed to Bosnia in December 1993, Nordbat 2 found itself in its first serious hostile encounter. A Swedish platoon was sent to relieve a Canadian company which was providing security for a mostly abandoned hospital compound in a remote area. As soon as the Canadians left, a Croatian battalion-sized unit showed up and promptly mined the only road leading to the compound, ensuring that the Swedes would be unable to receive reinforcements.

Then they issued an ultimatum: hand over the three Muslim nurses, and we will leave you alone. The Swedish platoon leader, Captain Stewe Simson, radioed battalion command, and was told that it was his call to make, since he was the one in charge at the location. Captain Simson refused to hand over the nurses and instead ordered his men to prepare for combat.

Vastly outnumbered and outgunned, Captain Simson realized that it was unrealistic to expect that his unit would survive a full-out assault. Nevertheless, he was determined not to give in. The Croats started to fire mortar rounds, but the Swedes held their positions. After a few hours, the Croats issued a new ultimatum: the nurses could stay if the Croats were granted free passage to the compound. Again, Captain Simson refused. The situation remained tense throughout the night, with the Swedes maintaining full combat readiness. In the morning, the Croats negotiated with the Swedes and eventually left, quietly dropping their ultimatums. Nordbat 2 had shown resolve even in the face of hopeless odds, achieving a strategically important victory as a result of a decision made by a platoon commander.

Other incidents followed. When fired at, Nordbat 2 often shot back, frequently disregarding the UN rules of engagement. Colonel Henricsson made it clear that he would not respect rules and regulations that threatened to prevent him from achieving his mission objectives. When his own government tried to rein him in, he simply told his radio operator to pretend that the link was down until he had a fait accompli to present to Stockholm.

In one particularly infamous incident, the Bosnian Serb Army set up an ambush for the battalion’s Danish tank company. By launching a feint attack against a remote outpost, the Bosnian Serb Army lured a detachment from the tank company to drive straight into a trap. Anti-tank missiles and heavy guns opened up from concealed positions. Once the Danes started to take fire, their response was furious. The detachment commander simply told his crews to neutralize the anti-tank positions. The Leopard tanks directed accurate and deadly fire against the Bosnian Serb Army positions, using up no less than 72 main gun rounds. One by one, the anti-tank missile batteries and gun positions fell silent. During the fight, a Bosnian Serb Army ammunition supply was hit, resulting in a large explosion. After the engagement, Nordbat 2 estimated that as many as 150 troops may have been killed, although the Bosnian Serb Army denied this.

The incident greatly upset the UN regional command, which threatened to relieve Nordbat 2′s battalion commander and have him sent back to Sweden. Nevertheless, Nordbat 2 had once again refused to let the parties to the conflict dictate the terms of its deployment. In several other incidents, Nordbat 2 personnel intervened to protect refugees and took action to prevent the cover-up of ethnic cleansing operations. On several occasions this took the form of forcing passage through roadblocks. During one such event, the battalion commander himself forced a sentry to remove the anti-tank mines used to block passage by threatening to blow the sentry’s head off with a heavy machine gun.

The lithium-metal battery with this architecture had an energy density of 560 Wh/kg

Monday, October 4th, 2021

One of the more promising possibilities for improving lithium-ion batteries involves swapping out the graphite used in one of the battery’s electrodes for pure lithium metal, a material that can hold as much as 10 times the energy:

The researchers started off with what’s described as a cobalt-poor, nickel-rich layered cathode (NCM88) and a commercially available organic electrolyte called LP30. While the cathode reached high energy density, instability soon took hold and storage capacity decreased as the battery was cycled.

“In the electrolyte LP30, particles crack on the cathode,” explains Professor Stefano Passerini, Director of HIU. “Inside these cracks, the electrolyte reacts and damages the structure. In addition, a thick mossy lithium-containing layer forms on the anode.”

So the team swapped out the LP30 electrolyte for an alternative, and one that brought about profound gains in performance. Described as a non-volatile, poorly-flammable, dual-anion ionic liquid electrolyte (ILE), this ingredient proved to largely avoid the structural defects on the cathode and saved the battery from the fatal electrochemical reactions.

[…]

The lithium-metal battery with this architecture had an energy density of 560 Wh/kg. For context, there are research consortiums dedicated to breaking through the 500-Wh/kg density threshold in order to power next-generation electric vehicles, while today’s best-in-class lithium-ion batteries have energy densities of 250 to 300 Wh/kg.

Forty-nine are cute quirks, and one is destroying civilization

Sunday, October 3rd, 2021

Julia Galef, author of Scout Mindset, earned her celebrity status honestly, Scott Alexander quips, through long years of hard labor in the rationality mines:

Back in ~2007, a bunch of people interested in biases and decision-making joined the “rationalist community” centered around the group blogs Overcoming Bias and Less Wrong. Around 2012, they mostly left to do different stuff. Some of them went into AI to try to save the world. Others went into effective altruism to try to revolutionize charity. Some, like me, got distracted and wrote a few thousand blog posts on whatever shiny things happened to catch their eyes. But a few stuck around and tried to complete the original project. They founded a group called the Center For Applied Rationality (aka “CFAR”, yes, it’s a pun) to try to figure out how to actually make people more rational in the real world.

Like, a big part of why so many people — the kind of people who would have read Predictably Irrational in 2008 or commented on Overcoming Bias in 2010 — moved on was because just learning that biases existed didn’t really seem to help much. CFAR wanted to find a way to teach people about biases that actually stuck and improved decision-making. To that end, they ran dozens of workshops over about a decade, testing various techniques and seeing which ones seemed to stick and make a difference. Galef is their co-founder and former president, and Scout Mindset is an attempt to write down what she learned.

Reading between the lines, I think she learned pretty much the same thing a lot of the rest of us learned during the grim years of the last decade. Of the fifty-odd biases discovered by Kahneman, Tversky, and their successors, forty-nine are cute quirks, and one is destroying civilization. This last one is confirmation bias — our tendency to interpret evidence as confirming our pre-existing beliefs instead of changing our minds. This is the bias that explains why your political opponents continue to be your political opponents, instead of converting to your obviously superior beliefs. And so on to religion, pseudoscience, and all the other scourges of the intellectual world.

But she also learned that just telling people “Hey, avoid confirmation bias!” doesn’t work, even if you explain things very well and give lots of examples. What does work? Research is still ongoing, but the book concentrates on emotional and identity-related thought processes.

[…]

Instead of thinking “I’m sure global warming is fake!”, try to think in terms of probabilities (“I think there’s a 90% chance global warming is fake.”) Instead of thinking in terms of changing your mind (“Should I surrender my belief, and switch to my enemy’s belief that global warming is true”), think in terms of updating your probabilities (“Now I’m only 70% sure that global warming is fake”). This mindset makes it easier to remember that it’s not a question of winning or losing, but a question of being as accurate as possible. Someone who updates from 90% to 70% is no more or less wrong or embarrassing than someone who updates from 60% to 40%.

[…]

A lot of the best rationalists I know instinctively apply these tests to everything they think. One technique for cultivating this practice (not the book’s recommendation) is to go on Twitter, where the adage is “there’s always an old tweet”. Argue that people who say racist things should be cancelled, and someone will dig up your old racist tweet and make you defend why you shouldn’t face the same consequences. Argue that it’s disgraceful when the other party uses extreme violent language about their outgroup, and someone will dig up an old tweet where you used even more extreme language about yours. Demand that the Republican senator resign for sexual misconduct, and someone will find the old tweet where you said the Democratic senator should tough it out. Eventually, if you want to maintain any dignity at all, you learn to double-check whether your beliefs are consistent with one another or with what you’d believe in vaguely similar situations.

Scout Mindset says: why not try the same thing, even when you’re not on Twitter, just to determine what’s true?.

And one very likely answer is: because it would hurt.

Scout Mindset tries to differentiate itself from other rationality-and-bias books by caring a lot about this. It argues that, while other rationality books just told you what to do, most people wouldn’t do it; they’d be too emotionally attached to their existing beliefs. So after giving a few intellectual suggestions, it goes on a deep dive into the emotional side.

[…]

It reminds me of C.S. Lewis — especially The Great Divorce, whose conceit was that the damned could leave Hell for Heaven at any time, but mostly didn’t, because it would require them to admit that they had been wrong. I think Julia thinks of rationality and goodness as two related skills: both involve using healthy long-term coping strategies instead of narcissistic short-term ones.

[…]

Julia is trying to normalize changing your mind, to assure you that lots of great people who you respect do it, that there are whole communities out there of people who do it, that she does it and she is a TED-talk-having celebrity who you implicitly trust.

Big money for container carriers

Saturday, October 2nd, 2021

Two years ago, a 40-foot container cost less than $2,000 to transport goods from Asia to the U.S:

Today the service fetches as much as $25,000 if an importer pays a premium for on-time delivery, which is a luxury. That’s translated into big money for container carriers, with the industry on track to post $100 billion in net profit this year, up from about $15 billion in 2020, says John McCown, an industry veteran and founder of Blue Alpha Capital.

Harden’s Folly

Friday, October 1st, 2021

Steve Sailer describes Kathryn Paige Harden’s The Genetic Lottery as Harden’s Folly:

After years of trying out on the science conference circuit her arguments for why the Woke shouldn’t be so anti-genetics, The Genetic Lottery is finally here. It turns out to be an elaborately contrived triple-bank-shot attempt to head off growing Ibram X. Kendi-style science denialism by claiming that ignoring the influence of genetics upon human differences just enables the Real Bad Guys, led by archvillain Charles Murray, to easily dunk on the libs:

When social scientists routinely fail to integrate genetics into their models of human development, they leave space for a false narrative that portrays the insights of genetics as a Pandora’s box of “forbidden knowledge.”… Why would we want to hand people opposed to the goals of social equality a powerful rhetorical weapon, in the form of a widely prevalent and easily understood methodological flaw in social research?

[…]

The Genetic Lottery is all over the map. Some people try not to get canceled by adopting an obscure prose style. Harden, instead, artlessly expresses herself, and then goes back and says the opposite later.

[…]

Harden is proud of her book’s title:

A lottery is a perfect metaphor for describing genetic inheritance: the genome of every person is the outcome of nature’s Powerball.

But, except for the potential big payoff, lotteries are boring. In contrast, how a particular baby gets made is fascinating on multiple levels: scientific, sociological, romantic, and erotic. A less bad metaphor for how humans are conceived would be poker, a game that combines luck, strategy, and psychology. Murray, by the way, plays poker.

Moreover, Murray is an Aristotelian. The Greeks valued excellence not just for what it could do for the poor, but for its own sake.

This can lead to excessive Nietzscheanism. Yet, Harden’s Rawlsian conviction that society must be organized around helping the lowest potential people narrow gaps seems comparably unbalanced. The old Benthamite notion of the greatest good for the greatest number seems more sensible (but is out of fashion for its majoritarianism).

Harden propounds a sophomoric view that intelligence is “socially valued, not inherently valuable,” and follows that up with a conspiracy theory that early-20th-century eugenicists plotted to get us:

…to see intelligence (as measured on standardized IQ tests) and educational success, perhaps more than any other human phenotypes, in terms of a hierarchy of inferior and superior persons is not an accident. It is an idea that was deliberately crafted and disseminated.

In truth, intelligence has been viewed as valuable for a lot longer than that. For instance, the most famous work of ancient philosophy, Plato’s Republic, is basically about why philosophers deserve to be kings.

More reasonably, the Greeks felt it smart to invest the most in the education of the highest potential students. Thus, it used to be seen as a good thing that Plato had Socrates for a teacher and Aristotle for a pupil. Similarly, society invested heavily in the young Harden’s potential, granting her a full ride to a private college due to her high test scores.

The ideology of The Genetic Lottery seems motivated in sizable measure by Harden’s maternal feelings for her two very different children. One of her children is healthy and bright, while the other, to whom Harden devotes more of her efforts, was born with a congenital defect.
